PUMP-ROD BALANCE.

QPEGIFIQATION formingpart of Letters Patent No. 685,617, dated October29, 19 01.

Application filed March 27, 1901. Serial No. 53,063- (No model.)

To all whom it may concern:

Be it known that LARTHUR A. KooH, a citizen of the United States, and aresident of Montezuma, in the county of Poweshiek and State of Iowa,have invented a new and Improved Pump*Rd Balance, of which the followingis a full, clear, and exact description.

This invention relates to balancing devices for pump rods operated indeep wells by Wind-wheels or any power, the object being to provide asimple device for balancing the weight of the water and pump-rod abovethe cylinder in the well, thus increasing the power and materiallyaiding the operation of the wind-wheel on the upward stroke of thepumprod.

I will describe a pump-rod balance embodying myinvention and then pointout the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters'of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of a balancing device embodying myinvention. Fig. 2 is a section on the line a: 00 of Fig. 1, and Fig. 3is a section on the line 3 y of Fig. 1.

Referring to the drawings, 1 designates the windmill-tower, of theusualconstruction,and 2 indicates the pump-rod. Arranged in the lowerportion of the toweris a frame consisting of the side sections 3 and 4,which are preferably made of angle-iron, as shown. The central portionsof these frame-sections are turned inward, and the outerends areconnected to the cross-bars 5 of the tower by means of hook-bolts 6.These hook-bolts are passed through openings in the frame-sections andengage around the under sides of said cross-bars. By this constructionthe frame may be readily removed or attached. The frame is made rigid bymeans of bracerods 7, extended from the frame-sectionsupward toconnections with the cross-bars 8 of the tower, and short braces 9extend from the frame-sections to connections with the long braces 7.The short braces are secured to the long braces by means of bolts, whilethe long braces are secured to the cross-bars 8 also by means of bolts,and the braces may be provided with a number of holes, so that the framemay be adjusted to the distance between the upper and lower cross-barsof the tower.

Arranged on opposite sides of the pumprod are racks 10 and 11-. 1 Eachrack'is concaved or trough-like on its inner side to embrace thepump-rod, and the racks are held in position by means of bolts 12,passing through the ends of said racks and also through the pump-rod.They maybe further held from possible displacement on the pump-rod bymea ns'of lugs 13, extended from the inner surfaces of the racks andengaging in notches formed in the pump-rod.

Mounted to swing in the frame comprising the sections 3 and 4 are thesegment-gears 14 and 15. The segment-gear 14 engages with the rack 10,and the segment-gear 15 engages With the rack 11. Arms 16 and 17 extendoutward from the segment-gears, and adj ustabl y mounted on these armsare weights 18. The object in making the weights adjustable is toprovide for the force or power of the windwheel and to balance theweight of the water wells.

In operation as the pump-rod moves downward the racks will operate thesegment-gears to swing the weights 18 upward. Then as the rod is movedupward by the wind-wheel the 1 weights 18 will materially aid in theupward of the pump-rod the said rod is evenly balanced and will be heldin a straight line in its movement. In other words, it will not bedeflected or bent, as might be the case were a weighted lever placed atone side only.

Having thus described my invention, I claim as new and desire to secureby Letters Patente 1. In a pump-rod balance, racks applied to oppositesides of the pump-rod, segment-gears engaging with said racks, a framein which said gears are mounted, arms extended outward from the gears,and weights adjustable on said arms, substantially as specified.

2. In a pump-rod-balancing device, racks connected to the pump-rod,segment-gears engaging with said racks, a tower, a frame consisting oftwo sections secured in the tower and having their central portionsextended 1nward, the said segment-gears being mounted to swing betweenthese inwardly-turned portions, weighted arms extended from thesegment-gears, and braces extended from the frame-sections toconnections with the tower, substantially as specified.

3. In a pn [holed-balancing device, a tower, a frame comprising twosections, hook-bolts at the outer ends of said frame-sections forengaging with cross-bars of the tower, braces extended from saidframe-sections to connections with cross-bars of the tower, short bracesextended from said frame-sections to connec tions with the first-namedbraces, segmentgears mounted to swing in said frame, weighted arms onsaid segment-gears, and racks on the pump-rod with which saidsegment-gears engage, substantially as specified.

4. The combination with a pump-rod, of racks on opposite sides thereof,said racks having concaved inner surfaces to fit around the rod, lugsextended from the inner sides of said racks for engaging in notchesformed in the rod, and weighted segment-gears engaging with said racks,substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
